COMBINED JACK AND PULLER.

To aZZdu/zom it mag concern.- 7

Be it known that I,- ARTHUR E. CLnMnN'rs, a citizen of the-United States, residing at South Jacksonville, in the county of Duval and State ofFlorida, have invented new and useful Improvements in Combined Jacks and Pullers, of which the following is a its upper portion forined witli barrels whose bores are threaded and whose. confronting surfaces are grooved longitudinally to provide guides. for a stem or shank that has an outstanding lug passing between the guides, said lugs serving as a rest for anelement to be elevated or having, attached thereto, a chain provided with grapple hooks to, engage with the stump of a tree to ber-aised, the shank havingits; upper portion provided with a lateral-portionprovided with spaced openings through which pass the nonthreaded ends of screws that enter the referred to threaded openings in the barrels. On the non-threaded ends of the screws are worm wheels whichrest on the top surface of the head, the said worm wheels being engaged by a Worm o-n a-shaft that is provided with an operating handle, and the turning of this shaft will cause the turning of the screws and the longitudinal movement of the head and shank and the engaging ele ment or elements carried thereby,

The foregoing, and other objects which 1 will appear asthe nature of the invention is better understood, may be accomplished by a construction, combination and operative arrangement of parts, such as is illustrated,

by the drawings which accompany and which form part of this application. 7

In the drawings Figurel is. a view showing the device employed for pulling the stump of a tree- F 1g. 2 is a view of the device employed as an ordinary vehicle jack.

Fig. 3 is a front elevation of the improvement.

{As disclosed by the drawings, the body portion '1 of the improvement has depending from its lower corners outwardly directed downwardly roundedlegsj2. The

outer end' of'each of thelegs has a flat sub- .'stantially square or rectangular enlargement providing the same with 'What I will refer to as foot portions? Thefoot portions 3' prevent the legsifrom sink-ing. into the ground, when the device isv employed as a stump puller, as'. illustrated in Fig. 1 of Also the foot portions provide a firm supportfor the device when employed as a jack, as ill-ustratedin Fig. 2 of the drawings. The body 1 is of a substantially rectangular formation, having its outer face flat, but'its'inner face, from its barrels 4:; By reference to, the drawings,. it

corners. rounded, providing whatl will term willbeseen th'atthe. barrels, on the inner face off the body are spaced a suitable dis tance away from each other, and also that each of the barrels has a vertically disposed slot 5 that terminates with the inner straight wall, 6 of the body 1. These alining slots provide guideways for a cross sectionally rectangular shank 7. The shank may be of any determined length, and has at its outer end a widened and laterally extending portion which I shall term a head 8. The head has adjacent its ends, round openings therethrough, and through these openings pass the non-threaded portions 9 of screws 10. The portion 10 of each of the screws, which proj ects beyond the head has keyed or otherwise secured thereto a worm wheel 11. Between the worm wheels, the head is formed with spaced outstanding lugs 1212 respectiyely which have openings that provide bearings 5 integrally formed ment in its bearings by the contacting engagement of the ends of the worm with 7 positely pitched threads vertically the bearings 12. H

Each of the barrels has a vertical opening therethrough, the said openings being dis posed inward of the legs 2, and the openings are threaded to receive the screws 10 therein. These openings are indicated by the numeral 16 and the threads therein are pitched at opposite angles which is also true with respect to the pitch of the threads on the screws 10. Thus by turning the handle to V revolve the shaft the head 8 may be raised or lowered with respect to thebody, and effectively held at such adjustment by the coengagement of the screws with the threads in the bores of the barrels. t

On the inner face of the shank there is i an outstanding lug 17 which is guided'between the stralght' confronting walls of the barrels between the guide slots or grooves therein. This lug, whenthe device is employed as a jack, as illustrated in Fig. 2 of the drawings, en- "ages the portion The lug is formed with a transversenotch 18 from the upper edge thereof, the said notch being preferably widened and rounded at the lower portion thereof. This slot provides the lug withtwo engaging surfaces, -when the device is e'niployedas a jack and also serves as 'a means whereby an enlarged link 19 at oneend of a chain 20 may be received therein. The outer link of the chain has connected therewith grapple hooks 21'and these hooks are designed to engage with the trunk of th'e tree, when the device is employed as a stump puller. I

It is believedthat the construction and operation of the improvement will be peri fectly apparent to those skilled'inthe art to of a vehicle to be elevated.

spectively engaging resting which such inventions relate, by reference to the drawings, when taken in connection with this description, and that a further detailed description will not be considered necessary.

Having described the invention, 1 claim 1. In a device for the purpose set forth, a body having depending legs at the outer corners thereof, screw members having opthrough threaded openings in the body, a shank having an outstanding lug thereon guided through the body, a head on the shank having openings receiving the nonthreaded upper ends of the screws, worm wheels secured to said ends andrestlng on having a worm engaging the worm wheels, and an operating handle for the shaft. I

2. In a device for thepurpose set forth, abody having outwardly rounded a depending legs at theouter corners thereofterminating in fiat feet, said body having spaced barrels formed with threaded bores, on the inner face thereof, which are spaced. away from each other and whichhave the threads in their bores arranged at right and left hand pitches respectively, said-barrels having their confronting faces grooved, a cross sectionally rectangular shank guided through the grooves, havinga notched outstanding lug guided" between-the barrels, grapples removably secured'to the lug, a lateral head on the outer end of the shank, screws .hav-

movable said head, a shaft journaled in the head and ing'right and lefthand pitched threads re i'n' the bores of the respective barrels, said screws. having nonthreaded portions which pass through portions of the head, worm wheels secured to the last mentioned portions of the screws and on the head, spaced outstanding lugs on the head between the worm wheels and a shaft journaled thereirna worm on the shaft between the lugs engaging with the Worm wheels, and a removable operating handle for-the shaft. v. Intestimony whereof'I afli'xmy signature.
